The Vigneron submachine gun was developed during early fifties by the officer of the Belgian army and produced by Belgian company Precision Liegoise SA. It was adopted by Belgian army in 1953, and saw some combat in then-Belgian Congo. Vigneron submachine gun was quite conventional in design and appearance, and not much more can be told about this weapon.

Vigneron submachine gun is blowback operated, selective fired weapon which fires from open bolt. Fire mode selector / safety switch is located on the left side of the grip, just behind the trigger. It is interesting that in full automatic mode short pull on the trigger will still, produce single shots, and only a long pull will produce full automatic fire. Additional automated safety is built into the backstrap of the pistol grip. Cocking handle is located on the left side of the receiver, and is stationary when gun is fired. Ejection port has a spring-loaded dust cover. Barrel is relatively long and has two ports just behind the front sight base, which serve as a muzzle rise compensator. Sights are fixed, with rear aperture set for 50 meters range. Stock is made from steel wire and is retractable, with several positions so shooter can adjust it to his own preferences.
